Additional Considerations

Direct Drive vs. Belt Drive Pump

 

  • Direct drive pumps deliver higher cleaning power and efficiency
  • Belt drive pumps result in less maintenance, quieter usage and longer runtimes

Portable vs. Vehicle Mounted

 

  • Portable pressure washers are more maneuverable but are typically not as powerful
  • Vehicle-mounted pressure washers typically outperform portable models but cost more

Wands, Nozzles & Hoses

 

  • Pressure ratings must match your pressure washer's output
  • Attachments should be designated for hot water use (if applicable)
  • Smaller nozzle angles deliver more power but can damage delicate surfaces

Cleaning Chemicals
